What is

� Android is an OS (Operating System)� Like Windows 8 and Windows RT (Microsoft) and iOS (Apple)

� An OS is � the software that supports a computer's basic functions, such as scheduling tasks, executing applications, and controlling peripherals.

� The OS (plus hardware) determines what software (apps) will run� E.g., Android runs Android Apps, Windows run Windows software, iPad runs iOS apps, etc.

What are the Android devices� Smart phones

� Android “owns” the market� 52.5% share of Smartphone Sales US

� Phablets� Phablet is a smartphone form factor describing devices with a screen between 5 to 6.9 inches in size, designed to combine or straddle the functionalities of a smartphone and tablet, eliminating the need for two devices

� Tablets� 7” to 12” Screens

� 42.7% vs. 53.8% for iPad

What is Computer Architecture?

� Do I care?

� You want to be smart(er), don’t you?

� We are talking Intel x86 vs ARM CPU’s� (Central Processing Unit)

� This is the chip that executes instructions to make the computer do stuff

� PC’s run on Intel (or AMD) chips� These are CISC (Complex Instructions Set Computers)

� http://www.wisegeek.com/what-is-cisc.htm#

� Intel i7 processor has 731 million transistors

� That’s the chip on this HP Laptop

© JB Burke 2014

What is Computer Architecture?

� Tablets run on ARM chips� RISC Chip (Reduced Instruction Set Computer)

� Fewer transistors = lower power, longer battery life� http://www-cs-

faculty.stanford.edu/~eroberts/courses/soco/projects/risc/whatis/index.html

� The ARM 7 chip has 58,000 transistors� My tablet has a 5-core chip = 5 ARM processors

� 5x58,000=290,000Transistors (vs. 731 million?)

� Lots less power required

� One main characteristic of a quality tablet …� Long battery life

� 8 hours and up

© JB Burke 2014

Characteristics of a Tablet

� Touch friendly� Keyboard optional

� Keyboard adds to weight and bulk

� Portable� Light weight, travel friendly

� My wife carries her 7” Nexus in her purse

� Good battery life� 8 hours and up – preferably more!

� You’re not always near a power source

Tablet OS/Architecture� Apple iOS unveiled Jan. 2007 with iPhone

� iPad delivered in 2010

� Google plus other manufacturers formed the Open Handset Alliance (OHA) in 2007� About the same time as iPhone appeared

� First Android version delivered in 2008� Gained quickly on Apple because of free OS� More robust, customizable and unique than iOS but …

� A bit more complicated and steeper learning curve.� http://www.android.com/about/� http://developer.android.com/about/index.html

� Windows RT� Launched alongside Windows 8 on October 26, 2012� Kinda late & hasn’t gone very far (yet)

A bit about Google� If you have a Gmail account (email with

youraccountname@gmail.com) you will have useful capabilities.� You can synchronize:

� Contacts (Address list)� Your Calendar

� Across all your devices:o SmartPhoneo Android Tableto Laptopo Desktop

� This is very convenient to keep track of life in general

© JB Burke 2014

Also email …� Google email is built-in to Android tablets

� You must setup your account of course

� You can also add your other email account(s)� You’ll need basic account setup info for this

� Mail can be viewed and answered from multiple devices:� SmartPhone� Tablet� Laptop� Desktop

� I set mine up so my Q.com email can only be deleted from the server via my desktop computer – so I can save what I want to keep in mail folders.

Some Android stuff to know …

� There are multiple Android Tablet hardware manufacturers� Unlike the iPad – Apple only

� The manufacturers integrate the free Android OS with their hardware

� This makes them cheaper than iPad� They generally run all the Android Apps� The interface (what the screen looks like out of the box) varies

from manufacturer to manufacturer.� Each has a unique:

� Launcher� Home screen interface

� Let’s look at mine (ASUS TF300T Jellybean 4.2.1)

© JB Burke 2014

System Updates� Occasionally the Android OS needs to update itself

� Just like Windows updates� You should do this when it’s offered

� It will get to you in any case – it is PUSHED to you

� Can be a longish download – just let it run� Don’t let it run out of battery – plug it in!

� Puts an Android icon on the screen as it runs� Will add useful features, such as bug fixes, performance

improvements and security updates� Recently I had an update to mine (Jelly Bean – 4.2.1) that gave

me the option of updating my home screen� I like the new one better

Components of a Tablet� An ARM CPU

� These vary quite a lot� Single core (like one chip)� Dual or quad core (like 2 or 4 CPU’s on one chip)� Higher end tablets get more complex and faster CPU’s

� 1 or 2GB (gigabytes) (typically) of RAM � Random Access Memory� This is where your apps run� As always, the more the merrier (and the more expensive)

� Bluetooth connectivity� Short range wireless connectivity� For keyboard, headphones, etc.

© JB Burke 2014

Components of a Tablet

� Graphics (GPU) Graphics Processing Unit � Just another darn computer chip

� Puts text and pictures on the screen

� Faster GPU (in more expensive tablets) makes for smoother screen experience (esp. games, movies)

� Screen Size � 7”, 8”, 8.9”, 10”, 12+”

� Is bigger really better?

� Smaller is more portable

� Screen resolution� How many dots on the screen
